[NSRCA-discussion] SmallModels...goodforthefutureofthePatternEvent?

[Fred Huber]

The stall turn you can run out of power at the top and still complete it. 
(you NEED to run out of power at the top)

The vertical up line you have to make a sustained straight up line at 
constant speed and then have the "omph" left to make the same raius push to 
get back level as the radius used to pull into the up line.

1:1 power:weight would do the old Sportsman.  You need 1.5:1 to do that up 
line and have the power to wind compensate.

A Golberg Tiger 60 with a .61 2-stroke in the nose could to the old Sportman 
sequence. (with just problems due to wanting to roll with rudder input) 
With a .91 4-stroke.. (which gives a significant improvement in up-lines) 
It would be marginal at best.

My Quest 3D e-powered was fine for the old Sportsman sequence using 13X6.5 
at 800 watts.  For the new sequence I had to prop-up to 14X8, drawing 900 
watts.  (fortunately the motor, battery and ESC are rated for that)  I 
simply COULD NOT do the up line with the 13X6.5.
I put the E-powered Quest together specificly to fly sportsman, aiming at 2 
rounds per battery charge.  I now can't count on having the power to 
complete the second round. (longer sequence AND more power required to do 
it.)
